PrPdGe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Pr sites. In the first Pr site, Pr is bonded in a 12-coordinate geometry to six Pd and six Ge atoms. There are a spread of Pr–Pd bond distances ranging from 3.10–3.23 Å. There are a spread of Pr–Ge bond distances ranging from 3.20–3.37 Å. In the second Pr site, Pr is bonded in a 12-coordinate geometry to six Pd and six Ge atoms. There are a spread of Pr–Pd bond distances ranging from 3.26–3.34 Å. There are a spread of Pr–Ge bond distances ranging from 3.11–3.21 Å. In the third Pr site, Pr is bonded in a 12-coordinate geometry to six Pd and six Ge atoms. There are a spread of Pr–Pd bond distances ranging from 3.07–3.28 Å. There are a spread of Pr–Ge bond distances ranging from 3.16–3.36 Å. There are three inequivalent Pd sites. In the first Pd site, Pd is bonded in a 10-coordinate geometry to six Pr, one Pd, and three Ge atoms. The Pd–Pd bond length is 3.20 Å. All Pd–Ge bond lengths are 2.61 Å. In the second Pd site, Pd is bonded in a 10-coordinate geometry to six Pr, one Pd, and three equivalent Ge atoms. There are two shorter (2.61 Å) and one longer (2.67 Å) Pd–Ge bond lengths. In the third Pd site, Pd is bonded in a 10-coordinate geometry to six Pr and four Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.63–3.02 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six Pr and four Pd atoms. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six Pr, three equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.83 Å. In the third Ge site, Ge is bonded in a 10-coordinate geometry to six Pr, three Pd, and one Ge atom.
